No power

Battery light on when it was running? To store

Did all that. New battery

Ignition switch tested.

Did you ever figure out what was the issue

Did you end up figuring it out ??? This just happened to me

Did you end up figuring it out??? This same thing just happened to me it started drove it stopped to get coffee came back to car won't start no lights come on nothing

Yes. Turns out it was the fusable link from the starter to the alternator. I also had rust build up on the bolt it was connected to at the starter which may have been the cause of the link defusing.
